NAME

vimdiff - edit two, three or four versions of a file with Vim and show differences

SYNOPSIS

vimdiff
[options] file1 file2 [file3 [file4]]

gvimdiff

DESCRIPTION

Vimdiff
starts
Vim
on two (or three or four) files.
Each file gets its own window.
The differences between the files are highlighted.
This is a nice way to inspect changes and to move changes from one version
to another version of the same file.

In each window the 'diff' option will be set, which causes the differences
to be highlighted.
The 'wrap' and 'scrollbind' options are set to make the text look good.
The 'foldmethod' option is set to "diff", which puts ranges of lines without
changes in a fold. 'foldcolumn' is set to two to make it easy to spot the
folds and open or close them.

OPTIONS

Vertical splits are used to align the lines, as if the "-O" argument was used.
To use horizontal splits instead, use the "-o" argument.
